I have large lungs, and can be very loud, and where I live the eagles ridge soar whilst going from one place to another, at just a bit higher than the tree tops, mostly baldies here with the ocasional golden, and for fun I started, belowing EEEGULL strait up at them, and they do a double take WTF, pull a hard wing over to get a better look and the finnish there turn, and blast off down wind, so if you get the chance, punking eagles is a blast
